Fossil gastropods Campanile meneguzzoi Fuchs, 1870 from the Oligocene of the Eastern Rhodopes (Bulgaria)

The subject of the study are the fossil gastropods Campanile meneguzzoi Fuchs, 1870 (family Campanilidae), from the collection of the Regional Museum of History in Kardzhali. They were found in the area of the village of Sekirka, Kirkovo Municipality, at the Garga Tepe locality. These fossils are preserved in polymictic sandstones of the so-called Layer of acidic and medium-acid tuffs, tuffites, tuffaceous sandstones, and tuffaceous limestones included in the formation of secondary acidic volcanism. The age of these sandstones is Oligocene. Paleoecological traits of the fossil fauna indicate that this was a shallow reefal marine environment with a rocky-sandy bottom and abundant algae. The water was warm, with normal salinity. The publication provides new taxonomic data and clarifications, as well as information regarding the location and geological characteristics of the locality.
